When the summer heat becomes unbearable, portable air conditioners offer a convenient and cost-effective way to cool down any room without major renovations or permanent HVAC installations.

Suppose you’re searching for a reliable method to install a portable AC in a sliding glass door or need guidance on portable air conditioner installation for taller vertical windows. In that case, this comprehensive guide will walk you through the process from start to finish.
Why Choose a Portable Air Conditioner?
Portable air conditioners are an excellent solution for cooling single rooms or spaces not serviced by central air. They’re ideal for renters, travelers, and homeowners looking for cheap air conditioning solutions without the high upfront costs of traditional systems. In hot cities like Las Vegas, these units provide instant relief, especially with proper window sealing kits to prevent heat from seeping back inside.
The key to efficiency is properly installing a portable air conditioner. Let’s examine exactly how to do it.
Step-by-Step: How to Install a Portable Air Conditioner in a Sliding Window
1. Prepare Your Equipment
Start by selecting a portable AC unit appropriate for your room size. Most come with an exhaust hose, adapter, and a window kit. If you have tall sliding windows or doors (70 inches or more), consider purchasing an extended door kit like the one used in our installation guide.
Plug the unit into a grounded wall outlet to confirm power and functionality. Don’t turn it on just yet.

2. Assemble the Exhaust Kit
Locate the exhaust vent hose and connect it to the rear of the AC. These hoses often twist into place using threaded couplings—be sure the connection is tight to avoid air leaks.
Next, assemble the adjustable plastic panels that will fill the height of your window or door.Â
Ensure the interior-facing panel includes the wing nut lock, enhancing security and preventing external tampering.
Slide the panels together until they match the height of the opening. Don’t worry about small gaps; we’ll seal those in the next step.
3. Install the Panel in the Window or Door
Open your sliding window or glass door and place the assembled panel vertically into the gap. Extend the panels until they fit snugly from bottom to top. Push the window or door against the panel to hold it in place.
To enhance insulation, use weather stripping or silicone foam to seal minor air gaps around the edges. Most kits include this material, which can significantly improve cooling efficiency.
For added security, we recommend placing thumb locks or window stops on both the top and bottom tracks of your window or door. This prevents the panel from being removed or the window from being opened from the outside.
Final Steps: Power, Test, and Enjoy Cool Air
With the exhaust hose securely connected and the window panel in place, it’s time to turn on your portable AC unit. Cool air should blow from the front vents while hot air exits through the exhaust hose outside the window or door.
Check for hot air leaks around the exhaust port. If necessary, adjust the hose fittings or reapply weather stripping. You should notice a drop in room temperature within minutes, and your AC is now fully operational.

Installing Through a Sliding Glass Door? Here’s What You Need to Know
The process is nearly identical for homeowners looking to install a portable AC in a sliding door. Simply swap the window panels for longer, vertical ones from a door kit, and follow the same steps:
- Insert the exhaust adapter into the designated panel.
- Extend the door kit panels until they fill the vertical height.
- Use weather seal foam for airtight results.
- Add sliding door locks to secure the panel in place.
Portable AC units are versatile and work as effectively indoors as outdoors. Ensure the exhaust vent is well supported and the door seals tightly against the inserted panel.
